Question

对于位置查找，Google自动完成工作正常，但它会在全球范围内返回搜索结果。我想限制在1000米半径或城市中的搜索结果。我按照此google link集成了自动完成搜索。仅在项目

中使用以下代码

-(void)autoComplete
{
    GMSAutocompleteViewController *acController = [[GMSAutocompleteViewController alloc] init];
    acController.delegate = self;
 [self presentViewController:acController animated:YES completion:nil];
}
// Handle the user's selection.
- (void)viewController:(GMSAutocompleteViewController *)viewController
didAutocompleteWithPlace:(GMSPlace *)place {
    [self dismissViewControllerAnimated:YES completion:nil];
    // Do something with the selected place.
    NSLog(@"Place name %@", place.name);
    NSLog(@"Place address %@", place.formattedAddress);
    NSLog(@"Place attributions %@", place.attributions.string);
}

- (void)viewController:(GMSAutocompleteViewController *)viewController
didAutocompleteWithError:(NSError *)error {
    [self dismissViewControllerAnimated:YES completion:nil];
    // TODO: handle the error.
    NSLog(@"Error: %@", [error description]);
}

// User canceled the operation.
- (void)wasCancelled:(GMSAutocompleteViewController *)viewController {
    [self dismissViewControllerAnimated:YES completion:nil];
}

Answer 1

你不能100％限制它，但你可以通过指定它的东北角和西南角来优先考虑你的城市，这是代码

GMSAutocompleteViewController *acController = [[GMSAutocompleteViewController alloc] init];
acController.delegate = self;

CLLocationCoordinate2D northEast = CLLocationCoordinate2DMake(northEastLati, northEastLongi);
CLLocationCoordinate2D southWest = CLLocationCoordinate2DMake(southWestLati, southWestLongi);
acController.autocompleteBounds = [[GMSCoordinateBounds alloc] initWithCoordinate:northEast
                                                                            coordinate:southWest];

[self presentViewController:acController animated:YES completion:nil];

现在你将得到99％的结果属于你的城市。希望它会对你有所帮助。

添加Swift版本。

如果正在显示您的autocompleteController，请通过调用进行刷新 updateCoordinateBoundsOnAutoCompleteController（）

/* Returns Bounds */
func getCoordinateBounds(latitude:CLLocationDegrees ,
                                 longitude:CLLocationDegrees,
                                 distance:Double = 0.001)->GMSCoordinateBounds{
            let center = CLLocationCoordinate2D(latitude: latitude,
                                                longitude: longitude)
            let northEast = CLLocationCoordinate2D(latitude: center.latitude + distance, longitude: center.longitude + distance)
            let southWest = CLLocationCoordinate2D(latitude: center.latitude - distance, longitude: center.longitude - distance)

            return GMSCoordinateBounds(coordinate: northEast,
                                       coordinate: southWest)

        }

/* Refreshes AutoCompleteController */
func updateCoordinateBoundsOnAutoCompleteController(){
        autocompleteController.viewWillAppear(true)
        autocompleteController.viewDidAppear(true)
    }

限制Google自动完成API仅显示附近的位置
